SKU: YZTORQUE
1979-1982 Yamaha YZ 250; 79-83 YZ 400 465 490 Torque Reed Valve Spacer


This reed valve spacer moves the reed valve further from the cylinder. This typically gives the bike more low end power. It will also help if your air boot has shrunk and the carburetor needs to sit further back.

It is the correct 4 bolt pattern for these models:

1984-1992 Yamaha YZ 80 Mossbarger Reed Cage
SKU: MB-06-400
Why should I use the MOSSBARGER 8-PETAL REED CAGE? How will it improve my engine? These are viable questions that need to be answered with facts and not just false advertising copy. First, the MOSSBARGER 8-PETALL REED will improve the engine power throughout the entire RPM range, because it flows more air at any given RPM than the stock or any of the other after market reeds. This means better low-end power out of turns, and more mid and top-end speed for the straightaway. Secondly, the MOSSBARGER REED will make the engine easier to start, idle smoother, and in general will make the engine easier to tune. This is due to the higher air velocity (speed) and added airflow provided by the design of the reed cage.
